Description

Technical Field

[0001] The utility model relates to the technical field of rubber sealing component production, in particular to a rubber sealing component hydraulic molding device. Background Art

[0002] Rubber seals are mostly round rubber products, generally used for leak prevention. Rubber seals have high elasticity and slight plasticity at room temperature, and have excellent mechanical strength, low hysteresis loss, and low heat generation during repeated deformation, so they also have good flexibility resistance.

[0003] Currently, the production process for sealing rings requires pressure molding. Specifically, a pair of upper and lower molds, aligned with a core, are used to form a joint. The sealing ring material is placed into the molding cavity formed by the core and mold at high temperature. The upper mold is then used to extrude the material downward, thus producing a ring-shaped sealing ring. However, during the loading and unloading process, workers may be burned by the high temperature of the mold or hot press. Furthermore, the rubber seal cannot be quickly released from the mold after molding, affecting processing efficiency. Utility Model Content

[0024] In this embodiment, the pressurizing mechanism includes a first hydraulic rod 9 . A groove 10 is provided on the hydraulic press base 1 . The first hydraulic rod 9 is fixedly installed in the groove 10 . A push plate 11 is fixedly installed on the top of the first hydraulic rod 9 .

[0025] In this embodiment, the hydraulic drive mechanism includes two groups of second hydraulic rods 12, which are fixedly installed on the front and rear sides of the groove 10. A connecting plate 13 is fixedly installed on the left side of the fixed seat 6, and a T-shaped slot 14 is provided on the right side wall of the connecting plate 13. The T-shaped slot 14 is longitudinally distributed on the connecting plate 13, and a T-shaped block 15 is slidably installed in the T-shaped slot 14. The T-shaped block 15 is connected to the push rod of the second hydraulic rod 12, and the connecting plate 13 is driven to move by the second hydraulic rod 12, thereby driving the fixed seat 6 to slide on the support frame 5 through the connecting plate 13. During the hot pressing process, the second hydraulic rod 12 drives the fixed seat 6 to move to the bottom of the upper mold 4, and the fixed seat 6 is lifted upward as a whole by the first hydraulic rod 9, so that the upper mold 4 is docked with the lower mold 7. In the process of lifting the fixed seat 6 upward, the fixed seat 6 is moved vertically upward with the cooperation of the T-shaped slot 14 and the T-shaped block 15 to prevent the position of the fixed seat 6 from being offset.

[0026] In this embodiment, a plurality of groups of support wheels 16 are rotatably mounted on the top of the support frame 5 . The support wheels 16 are in contact with the fixing seat 6 , and the fixing seat 6 is supported by the support wheels 16 to slide on the support frame 5 .

[0027] In this embodiment, the lifting and flipping mechanism includes two groups of third hydraulic rods 17, which are fixedly installed on the front and rear sides of the support frame 5. The top of the push rod of the two groups of third hydraulic rods 17 is fixedly installed with a bearing seat 18. A clamping seat 19 is rotatably installed on the adjacent side of the two groups of bearing seats 18. A cylinder 20 is fixedly installed on the top of the clamping seat 19. A clamping piece 21 matching the clamping seat 19 is provided on the front and rear sides of the mold core 8. A motor 22 is fixedly installed on the end of the bearing seat 18 away from the clamping seat 19. The power output shaft of the motor 22 is connected to the rotating shaft of the clamping seat 19. During the blanking process, the second hydraulic rod 12 drives the fixed seat 6 to move to the left end of the support frame 5. At this time, the clamping piece 21 is located in the clamping seat 19, and the clamping piece 21 is squeezed by the cylinder 20. Then, the mold core 8 is pushed upward by the third hydraulic rod 17. After the mold core 8 is pushed up, the clamping seat 19 is driven to rotate by the motor 22, so that the mold core 8 is flipped counterclockwise 80-90 degrees, so that the blowing mechanism can blow the sealing ring off the mold core 8.

[0028] In this embodiment, the blowing mechanism includes a fan 23, which is fixedly installed on the top of the top cover 3. A diverter plate 24 is fixedly installed on the left side of the top cover 3. An exhaust pipe 25 is fixedly installed at the air inlet of the diverter plate 24. The other end of the exhaust pipe 25 is connected to the air outlet of the fan 23. Several groups of air nozzles 26 are fixedly installed on the diverter plate 24. The gas generated by the fan 23 enters the inside of the diverter plate 24 through the exhaust pipe 25. The gas inside the diverter plate 24 is discharged outward through the air nozzle 26. The discharged gas blows the sealing ring away from the core 8 and cools the core 8 at the same time.

The sealing ring detached from the mold core 8 is blown onto the baffle plate 28 and slides into the collection box 27 for collection, so as to facilitate subsequent edge removal operations.

[0030] The specific working process of the utility model is as follows: during the hot pressing process, the push rod of the second hydraulic rod 12 is retracted, so that the fixed seat 6 is located at the right end of the support frame 5, and then the fixed seat 6 is pushed upward by the first hydraulic rod 9, so that the lower mold 7 is docked with the upper mold 4, thereby realizing the preparation of the sealing ring. After the sealing ring processing is completed, the first hydraulic rod 9 is reset, and the fixed seat 6 falls back onto the support frame 5. Then the push rod of the second hydraulic rod 12 is pushed out, and the fixed seat 6 is pushed to the left end of the support frame 5. At this time, the clamping piece 21 is located in the clamping seat 19, and the clamping piece 21 is squeezed by the cylinder 20. Then, the mold core 8 is pushed upward by the third hydraulic rod 17. After the mold core 8 is pushed up, the motor 22 is started, and the motor 22 is driven by the motor 22 Drive the clamping seat 19 to rotate and flip the core 8 counterclockwise 80-90 degrees. When the core 8 flips, the fan 23 starts, and the gas generated by the fan 23 enters the diverter plate 24 and is discharged from the air nozzle 26, thereby blowing the processed sealing ring away from the core 8 and cooling the core 8 at the same time to prevent the staff from being scalded during the loading process. The sealing ring detached from the core 8 is blown to the baffle plate 28 and slides into the collection box 27 for collection. Then, the motor 22 is started again to rotate the clamping seat 19 back to the horizontal position, and then the third hydraulic rod 17 is reset. After the staff completes the loading, the second hydraulic rod 12 is reset, and the above steps are repeated to achieve continuous processing of the sealing ring.
